Has anybody run these "fully ported" 906 heads on the same flowbench as the OOTB Stealth heads? Seems like an awful lot of conjecture going on here. I've seen "fully ported" 906 heads that flow 30 cfm less than a good (280 cfm) OOTB Stealth and ones that flow 60 cfm more than a good OOTB Stealth. My dad can always beat up your dad until we get them in the same ring with the gloves on.
5 different sets of Stealth heads on my bench and I check calibration before every head I test and every set was 267cfm or less. Good for the money yes BUT.!!!!
